Front passenger brake caliper locks up

I suspect you have a rubber brake line that is failed. So what happens is when you apply the brakes, and the brake fluid pushes the caliper piston out the rubber line does not allow the fluid to return so the caliper sticks and then overheats. So if you have replaced all this and no change, I would replace the line and go from there.

Then I would flush the entire brake system because these fail one of two ways. Either age/wear or contamination. So if you have not flushed the fluid out, here is a guide that will help with that:

Check out the diagrams (below). Please let us know what happens.

Good afternoon,

Calipers can lock up from either the caliper itself or a failed brake rubber brake line.

The easiest way to tell is to pump up the brake pedal and when the caliper does not release, open the bleeder screw. If fluid comes out and the wheel frees up, it is the brake hose that is the issue.

I attached the procedure for changing the hose. It is the same for both sides.
